Preferred embodiment of the invention

In order to make the objects, technical solutions and advantages of the present invention more apparent, the embodiments of the present invention will be further described with reference to the accompanying drawings.

Embodiments of the present invention provide a malfunction prevention device for a vehicle active safety function, which is based on a global positioning system, and suppresses activation of an active safety function by a latitude and longitude signal of a global positioning system. Referring to FIG. 1, the suppression device 100 includes an active safety external environment sensor 101, a vehicle positioning information receiving unit 102, an active safety controller 103, and an active safety actuator 104.

The active safety external environment sensor 101 is used for detecting environmental information when the vehicle is running. Specifically, the active safety external environment sensor 101 may include an ultrasonic radar, a millimeter wave radar, a laser radar, a camera, etc., and the detected environment when the vehicle is traveling. The information may include the distance between the vehicle and the preceding vehicle, the speed of the preceding vehicle, the distance between the self and the rear vehicle, the speed of the rear vehicle, and the position of the lane line.

The vehicle positioning information receiving unit 102 is configured to receive current latitude and longitude information of the vehicle that is located by the global positioning system. Specifically, the global positioning system is, for example, a GPS navigation system, a Beidou navigation system, a Galileo navigation system, etc., and the global positioning system is used to locate the vehicle. Current latitude and longitude information of the time, and the vehicle locating information receiving unit 102 receives the current latitude and longitude of the vehicle positioned by the global positioning system For the degree information, the vehicle location information receiving unit 102 may be an in-vehicle GPS module.

The active safety controller 103 is connected to the active safety external environment sensor 101. The active safety controller 103 can be an ECU (Electronic Control Unit, or an on-board computer) or a controller independent of the ECU. The active safety controller 103 receives the target detection result of the active safety external environment sensor 101, and determines whether the vehicle requires active safety system intervention based on the target detection result. Active safety features can include Autonomous Emergency Brake, Adaptive Cruise Control, Lane Keep Assist, and other features that can be actively involved in control. The suppression device can also be applied to an Autonomous Driving Vehicle.

The active safety controller 103 is also connected to the vehicle positioning information receiving unit 102, and the active safety controller 103 receives the current latitude and longitude information of the vehicle transmitted by the vehicle positioning information receiving unit 102. The active safety controller 103 is pre-configured with a list of suppression locations, where the list of suppression locations includes latitude and longitude information of the location where the active safety misoperation occurs, and the latitude and longitude information of the active safety misoperation occurrence location in the suppression location list is preset in the vehicle initiative. In the safety controller 103, the list of latitude and longitude information of the specific suppression location can be obtained by statistical calculation by vehicle road test or user feedback.

As shown in FIG. 1 and FIG. 2, the embodiment of the present invention adds a vehicle positioning information receiving unit 102 to receive the current latitude and longitude information of the traveling vehicle positioned by the global positioning system, and real-time the vehicle. The current latitude and longitude information is passed to the active safety controller 103. When the active safety controller 103 determines that the vehicle needs active safety system intervention (for example, automatic emergency braking) according to the target detection result of the active safety external environment sensor 101, the active safety controller 103 sets the current latitude and longitude information of the vehicle with the preset. The latitude and longitude information in the list of suppression points is compared, and if the current latitude and longitude of the vehicle is found to be consistent with a certain latitude and longitude in the list of suppression points or within a certain range (for example, a range of 10 m in diameter), the active The safety controller 103 does not issue an active safety system intervention command (e.g., an automatic emergency braking command) to the active safety actuator 104, i.e., the active safety controller 103 will inhibit activation of the active safety function.

Active safety actuator 104 is coupled to active safety controller 103, which may include a brake system, a power system, a steering system, and the like. According to the above, if the current latitude and longitude of the vehicle is found to be inconsistent with a certain latitude and longitude in the list of suppression points or is not within a certain range (for example, a range of 10 m in diameter), the active safety controller 103 goes to the active safety executive machine. The construct 104 issues an active safety system intervention command (e.g., an automatic emergency brake command) by which the active safety actuator 104 performs an active safety function (e.g., automatic emergency braking).

It can be seen that the misoperation prevention device 100 of the vehicle active safety function described above sets the latitude and longitude information of the place where the active safety misoperation occurs in advance in the list of suppression points of the active safety controller 103, for example, when there is metal deceleration on the road. When the belt causes the vehicle to actively perform automatic emergency braking, the latitude and longitude information of the location of the metal speed bump is preset to the list of suppression points, and when the vehicle passes the metal speed bump, the activation of the automatic emergency brake is suppressed. The vehicle does not malfunction due to automatic emergency braking. Therefore, the embodiment of the present invention can suppress the activation of the active safety function of the vehicle at the occurrence location of the active safety misoperation by collecting the location where the active safety misoperation occurs and preset to the suppression location list of the active safety controller 103. To prevent active safety misuse, reduce user complaints and safety hazards of vehicle travel.

The list of latitude and longitude information of the specific suppression location can also monitor and collect the active safety function activation status of the moving vehicle through the vehicle networking system. As shown in FIG. 3, the suppression device of the embodiment of the present invention further includes a vehicle-mounted vehicle network transmission unit 105 and a malfunctioning operation unit 106, and the vehicle-mounted vehicle network transmission unit 105 is connected to the misoperation monitoring unit 106 and the vehicle positioning information receiving unit 102. When the vehicle generates an active safety function (for example, automatic emergency braking), the misoperation monitoring unit 106 collects on-site monitoring information of the occurrence location of the active safety function, and the vehicle-to-vehicle network transmission unit 105 will measure the latitude and longitude information of the place where the active safety function occurs. And on-site monitoring information is uploaded to the Internet. The erroneous work monitoring unit 106 is, for example, an in-vehicle camera, and the live monitoring information is, for example, a live video image of a place where the vehicle captures the active safety function of the vehicle. When the on-site monitoring information is uploaded to the Internet, the staff determines whether the active safety function is a malfunction according to the on-site monitoring information (for example, according to an image), and if the on-site monitoring information determines that the active safety function is a malfunction, The latitude and longitude information record of the place where the active safety function occurs is stored in the data center's suppression location list, and the data center's suppression location list is specifically used for recording the feedback of the user vehicle through the vehicle networking system and is determined to have an active security error. The latitude and longitude information of the place where the work occurs; if it is determined by the on-site monitoring information that the active safety function is not a malfunction, the latitude and longitude information record of the place where the active safety function is generated is not stored in the list of suppression points of the data center. That is to say, the list of suppression locations of the data center only stores the latitude and longitude information of the place where the active security misoperation occurs. Therefore, through the car networking system, different user vehicles It is possible to upload and record the latitude and longitude information of the place where the active safety misoperation of the respective vehicle has occurred, and record it in the list of suppression points of the data center, for all users to share and download the list of suppression sites.

The list of latitude and longitude information of the collected suppression sites may be updated to the user's vehicle in real time through the vehicle networking system, or may be updated to the user's vehicle by means of product software upgrades during vehicle maintenance. The specific implementation method of real-time updating and downloading to the user's vehicle through the vehicle networking system, as shown in FIG. 4, since the latitude and longitude information of the place where the active safety misoperation occurs has been collected and recorded through the vehicle networking system, it can be transmitted through the vehicle-mounted vehicle network. The unit 105 downloads the list of suppression locations recorded in the data center to the active safety controller 103 of the vehicle, thereby ensuring the real-time and accuracy of the data preset in the list of suppression locations of the active safety controller 103.

As shown in FIG. 2, an embodiment of the present invention further provides a method for suppressing a malfunction of a vehicle active safety function, including:

Detecting environmental information when the vehicle is running, specifically, using the active safety external environment sensor 101 to detect environmental information when the vehicle is traveling;

Receiving current latitude and longitude information of the vehicle positioned by the global positioning system, specifically, using the vehicle positioning information receiving unit 102 to receive current latitude and longitude information of the vehicle positioned by the global positioning system;

Specifically, the active safety controller 103 determines whether the vehicle needs active safety system intervention (for example, automatic emergency braking) according to the target detection result of the active safety external environment sensor 101;

When the vehicle needs an active safety system intervention, comparing the current latitude and longitude information of the vehicle with the latitude and longitude information in the preset suppression location list, the suppression location list includes latitude and longitude information of the location where the active safety misoperation occurs, specifically, the suppression The latitude and longitude information of the active safety misoperation occurrence location in the location list is preset in the active safety controller 103 of the vehicle, and the latitude and longitude information of the active safety misoperation occurrence location in the suppression location list is, for example, a vehicle road test or user feedback. Obtained by statistics;

If the current latitude and longitude of the vehicle is found to be consistent with or within a certain range of the latitude and longitude in the list of suppression locations, the activation of the active safety function of the vehicle is inhibited, that is, the active safety actuator 104 of the vehicle is not actively activated. Safety system intervention instructions;
